Endoscopy and ultrasonography of pyometra
Keywords: pyometra, mare, uterus
This image shows the appearance of pyometra in the uterus of a mare during postmortem examination. In this case the condition was supported by a progestogenic environment; two corpora lutea (arrows) being visible on the right ovary. If she had not been euthanized, this mare would have been treated with prostaglandins and physical drainage.

Pyometra may be characterized by a purulent discharge but often it is only discovered on routine ultrasonography. The pus in cases of pyometra is often highly echogenic due to its cellular content. However, as seen in the inset ultrasonographic images shown here, it can be remarkably non-echogenic. In such cases, endoscopy will ascertain the diagnosis (seen inset image at upper right).
